portion of the type bar I6. Each type bar I6 has. a round opening 22 in itsV lower enlarged portion to pivotally receive the hollow shaft 23 which has an angular longitudinally extending channel to receive the angular shaft 24 having the rounded ends 25 journaled in the side bars 6 and 1.

Of the type bars I6, there are in the present instance nineteen in number corresponding to theA nineteen depressions 9 having characters marked thereon to the left of the line l2 of the keyboard 8. The type bars i6 are spaced from one another predetermined distances corresponding to the distances between the depressions 9 on an imaginary common projected line. As an'instance, on a common projected line from the left kto the right, the depressions 9 on the left side of the line I2 of the kyeboardt will assume the following order:

..-q, 21,71, Z, W, S, 2, X; e, d, 3, c, 1", f, 4, v, t, s, b

for theupper caseV type and be spaced from one another with the greatest spacebetween the .letters G and B on said projected line whereas the type bars, I6 readingl from left'to right will succeed one another in the reversegorder` and be spaced tocorrespond to the distances between the depressions 9 aforesaid.

`Adjacent to the type bar I6 'having the type b and B, there will be Vxedonthe hollow shaft 23 the enlargement 26 of the arm 2l extending forwardly across the keyboard 8 to the front frame wall 4.V Onvthis bar 2l, there is slidably mounted the finger piece 28 having ysecured thereto the flexible arm 26 on the rear end of which is formed the selector nger I4.

Adjacent to the type barv I6 having Vthe type q and Q, there is xed on the shaft 23, the sleeve 30. From the plane face of the sleeve 30 to the plane face of the enlargement 26, there The shaft 23 with the type bars I6 .is slidably mounted on the shaft 24 Vand the type bars I6 are so positioned relative 'to the depressions 9 on the left handside of the line I2 that the registration of the selectorflnger I4 with adepression 9 will position a corresponding .type bar i6 in the printing position defined by the recessed portion 33of the guide plate G, see Fig. 6A.V I

The bar or lever 21 with the shafts 23 and 2li will rock about the axis of the shaft 24 to cause' the printing action to take place.v For this purpose, there is provided the trip lever Si! which is fixed on the shaft 35 journaled at its leit hand siderin the side frame wall Band at its right hand sidein the `bracket 36.

The trip lever 34 has the trip finger 31 jat its upper end to register vwith; the spur 2! of the type bar I6 which is positioned in printing position. The shaft 35 also has fixed thereon the projection 38 which is operatively connectedby the link 39 withthe projection 40 also iixedon the shaft 24. Consequently when the iinger 28 is depressed to eiect a printing action, the link;39 and trip arm34 .will cooperate to cause the type bar I6 to swing into impression position against theV resistance of the resilient lip 32 of the strip 3| in alinement with the typebarzselectedv as illustrated in Fig. 4 without effecting the movement of the remaining type bars i6 Von the shaft 23.

For returning the several parts to normal position, the spring i is provided connecting the shaft 35 with the end of the link 39 connected to the projection 45, see particularly Figs. 2 and 3., To serve as a limiting stop, the sleeve 36 cooperates with the side bar'1. to limit the movement `of the lever 2 so that the selector nger I4 cannot register with any depressions 9 to the right of the depression 9 bearing the type l1 and B. At most, if the selector finger i4 were Vcaused to register with thedepression 9 bearing they markings 5 and due to the space betweenthe type bar. carrying the type g and G `and the bar carrying the type b and B, no impression would be made and the operator would immediately realize his mistake.

The actuation of the platen P for line spacing and letter spacing andthe feed or" the printing ribbon 42 may be effected in the usual way and will now be described.

The' platen P has the usual finger manipulating knobs 42 at the ends thereofandhas its diminished portions between the knobs 42 and the platen P journaled in the upper ends of the bracket arms 'd3 and it which extend up from a base 45 having inclined longitudinal edges to cooperate with the bayonet slidewayformed at i6 and il in the'l casting fifi which has vertically extending inclined edges to cooperate with the bayonet slideway formed at Si and 5B in the rear wall member 5.

The casting l3- has a shoulderY 5l normally resting on the shoulder 52, of the re'ar wall 5 and so `maintained byY the springs`53, connecting theY casting i8 with the abutmentsi, only one spring 53 and one abutment 54 being shown..

The casting 48 is pivotally connected'by the links 55 with the rear ends of the shift levers 56 which are xed to the'sh'aft 57 journaled in the side walls 6 andi. The iront ends of the shift levers 56 terminate in the upright portions 58, each provided with a nger engaging key member 59 at its upper end, the upright portions 58 extending upwardly through the openings 6!! formedin Vthe keyboard 8 with the keys 59 located above the keyboard 8 as shown.y v

For shifting the platen to effect printing of the upper case type 2i! of the type bars I 5, it will only be necessary to depress eitherv of the keys 59 thereby raising the casting 48 and with it the bracket arms 3 and 44 to position the platen.` vForconvenience the stops 66 are provided to accurately determine the upper position of the platen P when it is desired to print vupper case type 20. v

The line spacing of the platen is effected in the usual way, there being provided the toothed wheel 6l fixed concentric with the platen P to-be engaged by the friction creating spring 62. The letter spacer of the platen P is effected by the escapement now to be described.l

To the lower side of the-base Ad5, there is pivotally-connected the toothed rack 63 which is yieldably maintained iii-'engagement with the holding pawl E4 and the advancing pawl 65 by the Ilat spring 66 secured to the casting 48. The holding pawllLispivotally mounted on a pin 68 mounted on the casting i8V and is connected bythe spring 6'I tomaintain its toothed end in engagement with the teeth` of the rack S3. yThe stop pin 68 carried by thecasting 8 limits the movement of the pawl 64 to permit the rack V63 :energico` to be released by the finger piece 69 when returning the-platen `P for a newline. Y

:The advancing pawl ispivotally connected.

`.to 'the vlink -10'which is'pivotally mounted :on 'ae pin iextending upwardly-'from the 'faceof :the castingj48. -The paw/1:65 is .provided .with astop 1| normally pressed into engagement `with the edge ofthe link 18 bythe spring 12.V

Thek springV 13` on the othenhand vnormally urges the `link 18 Yawayfrom the rack .63` into engagement with the.abutment |14 at ythe upper end of thelever 14 fixed on the shaft 15' journaled in the side walls 6 .and 1.'.

S'Ihe 'shaft'15 has aV rearwardly extending arm -16 ixed thereto .and engaging the lower` face .of the spring. 11 securedto Athe inner face of-'the rear wall 5 yieldably to maintain the abutment 'I-14linengagement with the joint vformed by the engagement with a succeeding tooth on the rack 63 so that upon the release of the arm 1S, the spring 11 will return the arm 1liVv and the abutment |14 toactuate the pawl E5 to advance the rack -63 and therewith the platen P a letter space distance.

When vanfimpression is made, the lever 14 is similarly actuated, it 4being connected by the link 11 with the crosspiece 18 resting in the slot 19 of the trip lever 34, the crosspiece 18 engaging the bottom of the slot `19and being actuated for- Wardly with the trip lever 34 vwhen the'V finger piece 28 is depressed to effect an impression. Y The ribbon 42 is advanced from -the supply reel to the take-up reel 8|, thesupply reel^8|| beingpreferably rotatably mounted at thevupper endr of a post extendingy up from a fiangeV v2 projecting from the side wall S and the take-up reel 81| being preferably connected to rotate with'a post 82 pivotally connected to a-second flange 2 projecting from the side Ywall 1 and having fixed at1 its lowerjend a ratchet wheel 83 disposedab'ove an arm v84 also fixed to said post 82. To -a pin extending up from the plate 2 there -is pivotally connected a holding pawl maintained in engagement with the ratchet Wheel 83 by the spring 86. On the arm 84 there is pivotally mounted an advancing pawl 81 maintained in engagement with the ratchet wheel l85| by the spring 88. '-Ilhe arm 84 is operatively connected by the link 89y with: the downwardly extending projection xed to the shaft 15. f l l From the foregoing, itwill thus appearfthat whenever the shaft 15 is rocked, a letter space of the platen P Vwill be effected and fthe feed of ribbon 42'eiected.

For letter Aspacing the platen P without effect-- ing an impression, the Space .bar VI I may be depressed in the usual way, it being connectediby the rearwardly extending bars '9|' and 92A with the. sleeve'93 rotatably mountedon the 'shaft 51, which sleeve 93 in'turn is provided with a rearwardly extending arm 94, the rear lendof which is adapted to engage the lower face ofthe arm is supported by the shaft 15` and sleeve 93, Athe the ends oflsaid` bracket 38.

-, The `mechanisn'o associated with the type {ba-rs :I5 is substantially thesame as "that associated Withfthe Vtype vbars) 'I6 except in the` following respects mainly. The angular shaft 95,: lin place of the shaft 24 for 'the type bars IG, is journaled at its endsin the side walls 6 and 1-forwardly and `downwardly relative Vto the shaft 24. The type bars I5 -consequently arev hookedfshape', see

Yparticularly Fig. 2, to clear the type heads ofthe type bars I6. The trip lever 96, in place o'ffthe trip rlever 34. is shorterVV than the trip lever34` and is fixed to the hollow shaft 81, see .particularly Fig. 3, one end of whichshaft '91 is journaled on Vthe diminished end ofthe :shaft 35 ,and also ,journaled in the intermediate portioniof vthe bracket V38 adjacent Ato ,the endcf the 'shaft-:35, while the other end of the shaft 91 .is journaledV in'the sidewall 1,.

vThe crosspiece 18 also vcooperates with.' athis Vtrip lever -91 extending through the slot 98, vs'ee Fig. '2, alining with the slot 19 o'f lthetrip 'lever l 34 rin position of rest.
